salt-excreting |
|
exudation |
|
Accumulating salt and discharging it directly to the exterior in a concentrated aqueous solution, the salt then crystallizing on the exterior following evaporation of the fluid medium; when salt-excreting glands are indicated in the nominative, usually they are called simply salt glands. |

exudation |
|
Producing and secreting nectar; when glands are nectariferous, they are usually indicated nominatively as nectaries. |
|
enzymatic |
|
exudation |
|
Secreting a digestive exoenzyme; in carnivorous plants. |
|
oil-secreting |
|
exudation |
|
Producing and exuding an oily substance, often aromatic; when oil-secreting glands are indicated in the nominative, often they are called simply oil glands. |
|
glandular 2 |
|
exudation |
|
Anatomically distinct and producing and exuding a particular substance. |
|
laticiferous |
|
exudation |
|
Producing and exuding latex. |
|
scallop |
= crena |
FEATURE |
|
A rounded, marginal convexity or concavity in a series of such that alternate regularly and are oriented more or less perpendicular to the generalized perimeter of a laminar structure. See also sawtooth, sawtoothlet, scalloplet (crenule), tooth (dens), toothlet. |
|
laesura pl. laesurae |
|
FEATURE |
|
An elongate aperture in the proximal face of a spore at or near its pole, coterminous with a tetrad scar; in Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta. Depending upon tetrad configuration and resultant scar pattern, a laesura may be either unbranched or branched, the branches when present (usually 3) radiating from the pole and of approximately equal lengths. |
|
bundle scar |
|
FEATURE |
|
A smaller scar within the bounds of a leaf scar at the point where a vascular bundle traversed the abscission layer between stem and leaf. |
|
chamber (not recommended) |
= cell (not recommended), locule |
FEATURE |
|
Any structurally distinct compartment within an anther, ovary, fruit or other organ; not necessarily having any evolutionary integrity. |
|
stomium pl. stomia |
= stomatal pore |
FEATURE |
|
The opening in the wall of a sporangium, between the lip cells, through which the spores exit; in Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta. |
|
hilum 1 pl. hila |
|
FEATURE |
|
The scar left on a seed at the point of its abscission from the funiculus. |
|
crenule |
= scalloplet |
FEATURE |
|
A diminutive crena (scallop). See also dens (tooth), sawtooth, sawtoothlet, toothlet. |
|
scalloplet |
= crenule |
FEATURE |
|
A diminutive scallop (crena). See also sawtooth, sawtoothlet, tooth (dens), toothlet. |
|
hilum 2 pl. hila |
|
FEATURE |
|
The more or less central point within a starch grain of intracellular origin, about which the successive layers of starch were accreted more or less symmetrically. |
|
channel |
|
FEATURE |
|
A longitudinal, transversely rounded depression; esp. along the adaxial surface of a petiole or petiolule. |
|
fissure |
|
FEATURE |
|
A relatively narrow, split or crack in the outer tissue(s) of a structure. |
|
colpus pl. colpi |
= fossula, furrow, groove, sulcus, vallecula |
FEATURE |
|
An elongate depression that is relatively shallow and narrow. |
|
emargination |
= notch |
FEATURE |
|
A relatively small, acute sinus at the distal end of a laminar structure. |
|
macula pl. maculae |
= blotch, spot |
FEATURE |
|
An area that differs in color from the rest of a structure's surface, usually due to differing coloration. See also eyespot. |
|
notch |
= emargination |
FEATURE |
|
A relatively small, acute sinus at the distal end of a laminar structure. |
|
scar |
|
FEATURE |
|
A discontinuity in surface color and/or relief due to abscission of a structure formerly borne there. |
|
clinandrium pl. clinandria |
|
FEATURE |
|
The cavity in a floral column (gynostemium) within which the anthers are borne. |
|
commissure |
|
FEATURE |
|
Precisely, the joint or common boundary between the facing surfaces of two coherent or mutually appressed structures such as mericarps or stigmas, but traditionally (though imprecisely) applied to such a facing surface itself. |
|
blister |
= bulla, pustule |
FEATURE |
|
A relatively coarse, rounded protrusion or convexity. See also papilla. |
